James paused with the spoon over the beaker, before giving into temptation and tipping it it.
"Hell yeah, 270 pounds of stud coming up" he said, screwing the top on and shaking it up. Standing in front of the mirror, James prepared himself.
"Okay, here goes"
He then began to down the whole thing in one. When he finished, he dropped the shaker and wiped his mouth with the back of his wrist, before staring at his reflection. Nothing.
"Knew it was to good to be true"
But then, the marine felt a warm, tensing sensation, first in his chest, then it spread to his arms, torso, legs...
"Mierda..." blurted out James in surprise as he felt his muscles moving under his skin. James flexed his arms, which started to grow into bowling ball size before his eyes biceps, with thick meaty wrists on the end. His shoulders then swelled with muscle to become proportioante to his huge arms, stretching the tattoos on his shoulders.
"Aww yeah..." said James, feeling his back muscles widen, his shirt beginning to ride up, stretching and starting to split, as James' pecs pushed forward, making his shirt slip up over the huge mounds of muscle now sticking out from him.
Then, the muscly marine's torso began to thicken with defined cobblestone abs. James's glutes then exploded with muscle in his pants, forming big round globes, as his thighs became thicker then most mens waists, splitting the fabric of his pants , huge diamond shaped calves beneath that.
James looked at his hugely muscular body, his head sitting atop a massive meaty neck the same width as it. He was even a bit taller, now standing at 6"4.
"Woah... this is awesome". He flexed more, watching the veins pop up over his body, before heading towards the scale, feeling his new weight with every step.
"273 pounds. Holy shit". He looked at the powder in amazement. "I defiantly owe the sales guy some"
James walked back to the barbell he was using, and picked it up, surprising himself how easy it was. Before, this weight would've challenged him, now it felt like he could do double. Then James saw the other product, before looking down at his crotch, or at least trying to as he couldn't see much past his chest.
"Better make myself match down there as well."
